Smart and evil sounds more interesting, but then good and dumb is probably easier to keep amused.
I have a wife and kid, so does being evil mean that I’m evil to everyone, or just to people outside my personal circle, like Tony Soprano? Because if the latter, smart and evil would probably be able to provide for them better than good and dumb.
Regardless, if you have to be dumb, you should definitely be good. Dumb and evil is just a Fark headline (or a Darwin award) waiting to happen.
In a Christian paradigm, evil and smart is a paradox. Not witnessing. Don’t hurt me.
Evil and smart wins every time… I can’t stand real stupidity.
But with that slip you’ve identified yourself anyway!
Though a really smart person would have realized that, so maybe not…! 
I was thinking about this just the other day. I got annoyed at my 9-year-old daughter (who’s quite smart) for saying “I dunno, whatever” to some minor problem I presented her with. She’s not been in the habit of saying that before, and I told her that she should never dumb herself down. “I don’t care if your friends think it’s funny or cool to be stupid, you’re not and you should despise it. Don’t be nasty about it, but when you get right down to it, I’d rather you be a smart jerk of a person than a cheerfully stupid and nice person.”
It’s true, too. I like goodness, but I respect smartness, and while I aspire to exhibit both, I’d rather be respected than liked.
You mean, like the guy in Orange County who was caught on a surveillance camera in the act of stealing… the surveillance cameras?
He then drove his Mitsubishi pickup truck to get away, and when he heard that the cops were looking for him, he ditched it and stole a vehicle…
…another white Mitsubishi pickup truck!
But wait, there’s more. He attempted to cover up this theft by replacing its license plates with his own (ones that were registered to his name).
They don’t get made much dumber than this.
Smart and Evil, Smart and Evil all the way!
I soooo want to be the next Blofeld 
I’m even writing this from my underground lair! (or my basement apartment if you want to be nitty gritty, but the first one sounds cooler )
Thank you, that story just made my night. 
Put me down for good and dumb. Not much change from the present, really, but I digress…
At least I’ll be able to sleep soundly at night.
Smart and evil.
Smart enough, and nobody would know how evil you really are.
Smart and Evil. Why would I want to change now?
I believe I’ve been all of these things during my lifetime. Being dumb, as you have defined it, is not as painful as you might think. The pleasure of being ethical is more satisfying in the long run that the pleasure of being unethical. But I do miss being smart. Sometimes I forget about that person altogether.
Dumb and ethical.
Good and dumb. Many of my current recreational pursuits seem centered around making me dumber already, so I might as well take good as a bonus.
Why is it a bonus? As mentioned before (With examples), evil and dumb is at least entertaining. (For others, granted, but it serves a greater good than being dumb and good does.)
I don’t know if I’ve been good but I’ve been dumb my entire life; no point in changing now, even if I could.
